OmniSwitch 6850 issues connection via console port

[Xari]

Hello All,

I bought few used 6850 from ebay and they came completely locked, no access to web gui, telnet or ssh. I tried connecting with the console port with the following settings :
speed: 9600
databits: 8
stop bits: 1
parity : none
flow control : XON/XOFF
I tried using Putty and TeraTerm with no luck. When I power the switch i don't see nothing in the console window. Any suggestions how to factory reset this switch ?
Thank you

What powersupply did you have? Any LED at the front?
